With the introduction of adaptive deep brain stimulation (aDBS) for Parkinson's disease, new questions emerge regarding who, why, and how to treat. This paper outlines the pathophysiological rationale for aDBS, which provides real-time modulation of the stimulation amplitude based on subthalamic beta (range 13-30 Hz) activity and related physiomarkers. We review clinical evidence comparing aDBS with conventional DBS in terms of motor improvement, side-effect reduction, energy efficiency, and technical developments, including sensing-enabled device characteristics, stimulation algorithms, and potential clinical indications. We also discuss limitations, such as physiomarker variability, signal artifacts, and the absence of standardised programming protocols. Finally, we explore the readiness for clinical implementation and future directions, and estimate the scope of eligible patients. In our view, aDBS marks a fundamental change in approach from fixed stimulation towards physiomarker-guided neuromodulation. This evolution necessitates new infrastructure, clinician training, and real-world studies, but holds promise for more personalised and responsive treatment.

Effective treatments with deep and durable responses for relapsed or refractory marginal zone lymphoma (MZL) are lacking. The objective of the primary analysis from the MZL cohort of TRANSCEND FL was to evaluate the efficacy and safety of the CD19-directed chimeric antigen receptor (CAR) T-cell therapy lisocabtagene maraleucel.

Despite the availability of effective antihypertensive therapies, global blood pressure control rates remain unacceptably low. Contributing factors, such as low treatment adherence, therapeutic inertia, and rising multimorbidity, underscore the need for innovative approaches to improve hypertension care. New antihypertensive drug therapies that act on physiological pathways beyond those targeted by conventional drug classes are emerging. These therapies include small interfering RNA agents that inhibit angiotensinogen synthesis as a novel approach to inhibit the renin-angiotensin system, and new strategies to more selectively modulate aldosterone, such as aldosterone synthase inhibitors and non-steroidal mineralocorticoid receptor antagonists. There is also growing interest in therapies to enhance the action of the natriuretic peptide system. Although these innovations present valuable therapeutic opportunities, their benefits must be carefully balanced against considerations of safety, cost, clinical outcomes, and equitable access-all of which are crucial to reducing the residual burden of cardiovascular and chronic kidney disease.

Adult obesity has been linked to specific infections, but evidence across the full spectrum of infectious diseases remains scarce. In this multicohort study with impact modelling, we examined the association between this preventable risk factor and the incidence, hospitalisations, and mortality of 925 bacterial, viral, parasitic, and fungal infectious diseases, and estimated their global and regional attributable impact.
